After a recent episode with the battery on the Ranger out in Timbucktu and waiting 2 hours for a jump start, I thought that I wanted something small that I could keep handy in the truck and use in a pinch. Even though I have 2 jump boxes, I don't care to haul one of those around with me all the time. So after shopping, I ended up with the Schumacher unit above. Bought it from Wally World.com on "Rollback" for $35, which was $8. off the normal price. I hesitated because of the pricepoint, however I really liked the compact packaging of it, plus it was highly rated. Fast forward to today. At the gas station and a guy as me for a jump. After filling up, I went over to his car and hooked up the jump starter per the instructions. The car in question was an Accord 4 cylinder, and had small cables on it. Before he could even get into the car to start it, the negative clamp (plastic) exploded. After not being able to readily snap them together, I ended up dragging out my jumper cables and started it that way. Fortunately, I had the box and receipt with me. Wally now owns it once again. I didn't expect professional quality for the price, but I would have expected it to work at least once. Somewhat disappointed, as I have had good service with Schumacher products in the past. Back to the drawing board.
